2024年8月13日 · High ALT and AST are strong indications of liver disease, but what they tell us individually and together can be very different. This is because ALT is produced mainly in the liver, while AST is produced in the liver, brain, pancreas, heart, kidneys, lungs, and muscles.

2024年6月2日 · An AST/ALT ratio of less than 1 (where the ALT is higher than the AST) is a general indication of fatty liver disease. An AST/ALT ratio equal to 1 (where the ALT is equal to the AST) may indicate acute viral hepatitis or hepatotoxicity.

2025年1月18日 · Alanine transaminase (ALT). ALT is an enzyme found in the liver that helps convert proteins into energy for the liver cells. When the liver is damaged, ALT is released into the bloodstream and levels increase. This test is sometimes referred to as SGPT. Aspartate transaminase (AST). AST is an enzyme

2023年7月30日 · The liver function tests typically include alanine transaminase (ALT) and aspartate transaminase (AST), alkaline phosphatase (ALP), gamma-glutamyl transferase (GGT), serum bilirubin, prothrombin time (PT), the international normalized ratio …

2018年3月24日 · alt / ast Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) are enzymes found within liver cells at high concentrations. Raised ALT / AST levels in the blood occur in pathologies that cause liver cell (hepatocyte) inflammation or damage.

2024年9月7日 · What Are the Key Differences Between ALT and AST? The following table compares two liver enzymes, ALT (alanine aminotransferase) and AST (aspartate aminotransferase), focusing on their primary locations, cellular distribution, specificity, substrates, and clinical significance.

2024年1月22日 · AST, ALT, GGT, and ALP are indicators of liver inflammation and a first-line screening method for liver health. Regular assessments of these enzymes are important for detecting liver concerns early, allowing for timely intervention and management.

Liver function tests, particularly ALT and AST measurements, can help detect this condition. However, enzyme levels may only be slightly elevated in the early stages. The PPV of liver function tests for diagnosing fatty liver disease is relatively low, around 50%, as mild ALT and AST elevations can also occur in other conditions.

Normal (AST: 10-40; ALT: 7-56) No significant liver damage detected. N/A: Mild Elevation (AST: 41-100; ALT: 57-150) Possible mild inflammation or injury. Fatty liver disease, mild hepatitis. ... In cases where AST or ALT values skyrocket beyond normal ranges (>300), immediate medical attention becomes necessary due to potential life-threatening ...

While ALT and AST are both known as liver enzymes, AST is found in more areas of your body ALT. This is why if your ALT levels are higher, there’s a greater chance you have a liver condition than if your AST levels are higher.
